I live in metro Atlanta and have a 2-story home on a slab, approx. 2400 sq feet. I have 2-zone heating and air, with the 2 furnaces in the attic. The house and units (Trane) are over 21 years old, and although they still works, I think it's time to upgrade to new efficient units.
I've been happy with the Trane units, so I'm leaning that way, but I'm willing to take other suggestions.
But my first question is how much should I anticipate having to pay for 2 heating and 2 cooling units to be installed? I'd like to get general range of what it would cost before I start getting estimates. I'm looking for bottom-line for 2-zone
Second, any recomendations on the SEER rating that I should get for metro Atlanta (East Cobb county)? I'd like to go with the highest practical efficiency.
Third, should I opt for any of those "air-cleaning" add-ons, or are they not effective?
Finally, any recommendations on a local HVAC contractor?
Thanks in advance!
